Infective endocarditis presents differently in elderly patients, with distinct predisposing conditions and pathogens. Delayed diagnosis in older adults contributes to a poorer prognosis despite similar complication rates.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Geriatrics

Context:

  • Infective endocarditis (IE) is a serious infection affecting heart valves.
  • Clinical presentation and outcomes of IE can vary significantly with age.
  • Understanding age-specific features is crucial for effective management.

Purpose:

  • To compare the clinical features, causative microorganisms, and outcomes of infective endocarditis in elderly patients (>= 60 years) versus younger adults (< 60 years).

Summary:

  • Elderly IE patients more frequently had calcific aortic valves or artificial devices and higher rates of extracardiac disorders (e.g., neurological disease).
  • Staphylococcus epidermidis was more common in the elderly, while Streptococcus species predominated in younger patients.
  • Diagnosis was significantly delayed in the elderly, leading to a poorer prognosis despite similar rates of heart failure and embolic complications.

Impact:

  • The study highlights that while IE complications are similar across age groups, delayed diagnosis in the elderly, often with comorbidities, results in worse outcomes.
  • Findings underscore the need for heightened clinical suspicion and prompt diagnostic evaluation of IE in older individuals.
  • This research informs clinical practice and emphasizes age-specific considerations in IE management.
